The potential of Pseudomonas for bioremediation of oxyanions
(2021-12)
Non-metal, metal and metalloid oxyanions occur naturally
in minerals and rocks of the Earth’s crust and
are mostly found in low concentrations or confined
in specific regions of the planet. However, anthropogenic
activities ...
Transcriptional control of 2,4-dinitrotoluene degradation in Burkholderia sp. R34 bears a regulatory patch that eases pathway evolution
(2021-05)
The dnt pathway of Burkholderia sp. R34 is in the
midst of an evolutionary journey from its ancestral,
natural substrate (naphthalene) towards a new xenobiotic
one [2,4-dinitrotoluene (DNT)]. The gene cluster
encoding ...
Low CyaA expression and anti‐cooperative binding of cAMP to CRP frames the scope of the cognate regulon of Pseudomonas putida
(2021-03)
Although the soil bacterium Pseudomonas putida
KT2440 bears a bona fide adenylate cyclase gene
(cyaA), intracellular concentrations of 30,50-cyclic
adenosine monophosphate (cAMP) are barely detectable.
By using reporter ...
Pristine but metal-rich Río Sucio (Dirty River) is dominated by Gallionella and other iron-sulfur oxidizing microbes
(2017-03)
Whether the extreme conditions of acidity and heavy metal pollution of streams and rivers originating in pyritic formations are caused primarily by mining activities or by natural activities of metal-oxidizing microbes ...
Reconfiguration of metabolic fluxes in Pseudomonas putida as a response to sub-lethal oxidative stress
(2021-01-11)
As a frequent inhabitant of sites polluted with toxic chemicals, the soil bacterium and plant-root colonizer Pseudomonas
putida can tolerate high levels of endogenous and exogenous oxidative stress. Yet, the ultimate ...
Special Issue: Diversity of Extremophiles in Time and Space
(2021-11-30)
Extreme environments are fascinating ecosystems that have allowed us to increase
our knowledge about the evolutionary processes of life [1], develop new biotechnological
applications (e.g., industrial applications of ...
Phenolic variation among Chamaecrista nictitans subspecies and varieties revealed through UPLC-ESI(-)-MS/MS chemical fingerprinting
(2019-01-19)
Introduction
Comparative analysis of metabolic features of plants has a high potential for determination of quality control of active ingredients, ecological or chemotaxonomic purposes. Specifically, the development of ...
